El; Y., COEZPC-RZATION OF NEW JERSEY MINECAR Application filed Februaryfl, 1930. Serial No. 429,064. i

This invention relates generally'to mine cars and contemplatesthe provision of a mine car hav ng a relatively narrow .underframe.

Another object of the'invention is the pro-* vision of a mine car having a narrow underframe with the wheels arranged outside of the sills thereof and having body supporting elements secured to the ends of the sills, which body supporting elements are adapted to function as bumpers. Y v

Another object of the invention is the provision of a mine car having a welded body. i

A further object of the invention is to providea mine car which is strong and durable in operation and which is easy and simple to manufacture and to repair.

Other objects and advantages of this invention will be apparent from the following description, taken in conjunction with the accompanying drawings, in which Figure 1 is a top plan view of the car underframe;

. Fig. 2 is a side elevation of the car of the present invention; Fig. 3-is an end view of the car, the end gate thereof;

Flg. 5 1s a sect1onal View, showmg the car slde and a portionof the car floor; and

Fig; 6 is a sectional view, showing the car end and its attachment to the car sides and car bottom. a a j Referring now more particularlyto the drawings, a car of the presentinvention contemplates certain improvements on thercar shown in-my prior Patent No. 1,555,982 of October 6,1925, and comprises generally an underframe A, a body B and the wheels C.

The underfranie comprises sidesills, in dicated at 2, formed of Wood or the like and positioned relatively close together, as clearly shown in Fig. 1. The side sills are connected by end sills-4 and project beyond said end sills to form parts of bumper structures, the

remaining parts of the bumpers being formed by body supporting blocks, indicated at 6,

and arranged externally of the sills 2 at the the side sills.

ends thereof, said blocks beingsecured to the sills by bolts 8 which pass therethrough and through the sills and through flanges 10 V bumper plates are secured in position bythe before-mentioned bolts 8. For further connecting the side sills 2 and the blocks 6, tie rods 18 are provided having the securing nuts 19 andsaid tierods extend from the blocks 6 on one side of the underframe through the blocks 6 on the other side of the underframe, as clearly shown in Fig. 1.

The side sills are further strengthened by a plurality of cross-bearers 20, of which three are shown in the present instance, said cross-bearers being positioned and supported by flanged castings 22 secured by bolts 24 to In addition to the cross-bear ers, the side. sills are further connectedtogether by tie rods 26 which pass through castings 22 which support the central crossbearer, and said tie rods 26 also secure the spaced body supporting brackets 28 which extend outwardly from the side sills 2 and which are each providedwith a flange 30fby which they maybe securedby the tie rods, said brackets being arranged substantially midway between the ends of the underframe. Extending across the side sillsand secured to the loweredges thereof are metal plates 34, V

the side edges of which are flanged as at 36. These plates serve to reinforce the underframe, as will be apparent, and to these plates 14; at their lower ends are pins for an obvious purpose, said pins being secured in any suitable manner, as by means of the cotters 47.

For stiffening the underframe and for taking up haulage strains, a tie rod 48 is provided which extends through the several cross-bearers 20 and is fitted with securing nuts 49 at its ends.

The draft mechanism for the car comprises a pair of tie rods 50 at each end of the underframe which extend through the end sills and through the adjacent cross-bearer 20, said tie rods being provided with securing nuts 51 having bearing against wear plates 52 on the cross-bearer and against the plates 12 on the end sills. Draw. bars 5 1 extend inwardly through the end sills l and are mounted at their inner ends for yielding movement under draft strains. This mounting comprises the transversely extending followers 56 to which the draw bars are connected by pins 58.. The followers are mounted for sliding movement on the tie rods 50 and for movement with the draw bars, the draft springs 60 being mounted on the draw bars between the followers and end sills for an obvious purpose. Mounted on the tie rods on each side of the followers are front spacers 62 for preventing abnormal compressionofthe draft springs, w iile other spacers 6d are mounted-on the tie rods in the rear of the draw bars to define positioning abutments for the followers, as will be apparent; said spacers 64 having bearing against wear plates 65 on the cross bearers and through which rods 50 and 48 extend.

The body B of the car is preferably formed of steel and comprises the sides 66, one end 68..a floor sheet and an end gate 72.

The'floor sheet may be formed of a single sheet or of several sheets, as desired, and the sideredges and one end edge thereof are upwardly flanged as shown at 7 1 to externally lap thevlower edges of the side and end sheets 66 and 68, respectively, and said floor sheet is welded to the side sheets and end sheet as shown zit-76., The upper edges of the side sheets 66 and the end sheet 68 are provided with outwardly extending stiffening flanges 67-; and for stiffening the sides, vertically arranged channels 69 are welded thereto, as shown clearly in Fig. 5. The endsheet 68 has its side edges marginally flanged as shown at 71 to lap the ends of the side sheets 66, and said flanges 71 are welded to the sides as shown at 73. r I

The body. B is supported on the underframejand rests on the sills and is-secured thereto by the bolts l0, which, as before menwhich angle are mounted for pivotal movement in the upper ends of stakes 82, the low er ends of which latter are welded to the flange 74 of the floor sheet, as shown at 84. For securing the upper ends of the stakes, the same are welded to the upper flanges 67 of the side sheets 66 of the body.

The lower edge of the gate is flanged first outwardly, as shown at 88, and then upward- 1y, as at 90. and secured to the gate in such a position that the lower leg thereof rests on the flange is an angle 92, the lower leg of which is welded as at 94 to the upturned flange 90, and the angle itself is welded to the gate in the position shown, as indicated at 96-; the construction just described furnishing a reinforcing means for the lower edge ofv the gate. which is in effect a box girder. The ends of the angle 92 project beyond the side edges of the gate to define stops 98 which are adapted to engage the end edges of sides 66 of the body to prevent the gate swinging inside of the body, as will be apparent.

For latching the gate in closed position a chain link arrangement 100 is provided which is connected to a clip 102 welded to the floor of the car body and which. has an end link 10 i which extends through an opening formed in the gate, as clearly shown in Fig. l; said link 104 being secured in position by a pin 106 formed at the end of alatch lever 108 pivoted to the gate in a bracket 110. Pivoting of the lever will result in the pin leaving the link 10% and permitting swinging of the gate on its pivot.

Constructed as above, a car of the present invention is well adapted to withstand-the rough usage of mining service and may be easily and quickly repaired when necessary. The present car provides a. construction in which the wheels are arranged outside of the side sills and the car is, constructed cheaply and yet durably. It can be seen that the present construction provides a car underframe in which the car wheels may be arranged outside-of the side sills while the underframe is adapted to support a car body of usual. dimensions. that the flanged plates 12 arranged on the inner and outer surfaces of the end sills and which are connected at, their flanges to the side sills reinforce and stiffen the car underframe at the ends thereof. It can further be seenthat the ends of the underframe are reinforced and protected by means of rigid elements.- comprisingthe bumper plates 16 connected to the outer plates 12-; thisconstruction providing a metal covering extending'entirely across the ends of the underframe.
